The internet is a wonderful thing! Having been out of motorcycling for 20+ years (grew up dirt biking, MXing, Enduroing and Street riding) I jumped out and bought an 05 TTR125 (for the kids) and an 05 WR450. Shortly after the purchase I stumbled on TT. You guys are great! I can't thank you enough for the collective wisdom and advice and have spent a lot more money than I want at the TT store but they do have the best prices and great service. I wanted to pass on my experience with the mods for anyone that cares to hear from a definite amateur: Throttle Stop: bought the YZ for $10 at the dealer. Touchy to install, working blind with limited access but very doable. An immediate must MOD! TT AIS Removal: Not hard at all, didn't remove radiator, just unbolted it and stuffed hoses, minimum skinned knuckles but everything fit great. Plastic fitting takes patience. JD Jetting: Great Kit, very hard to work on carb without removing but I did it. Lots of twisting, all the parts fit great though. Good instructions. ZipTy Screw: Had to stop work and logon to figure out the aluminum blocking the hole but then twisted a small sheet metal screw in the hole and pulled it right out. Spring, washer and Oring fell right out and installed perfectly. Grey wire: Hard to get to the connector but ended up cutting the wire, taping both ends and re-taping the whole thing back in place. ProMoto Billet: Easy to remove stock "peashooter", easy to install Billet. Remember to enlarge hole per instructions. It's a little louder than stock but certainly not too loud. Enduro Eng. Handguards: Takes a little work adjusting cables etc., cutting grips (but I didn't take them off) but they are great! Solid and a must for the kids bike. (I never fall ) Unabiker Radiator Guard: Never had a 4 stroke, must less a radiator, but it seemed like a must. Please follow instructions explicitly. (They mount next to frame) or they won't fit and can cause a little swearing. Put them on right and they are great. Buy some bigger washers, don't know why they scrimp on that. Utah Skid Plate: Mounted very easily, didn't have any problems with the clamps and it sure is good protection. Adds a little noise but you get used to it quickly. BlueRidge ToolKit: Ordered the number 2 set (just ordered, haven't received) and it looks great. Expensive but not more than I would pay if I was broke down on the trail and needed tools! Suspension: I'm now entering that field and there's a whole lot to learn. I adjusted all clickers to what the manual said they should be (they weren't set to what they should be, not far off but a few clicks here and there), let the air out of the forks and tightened up the rear sag. I'll be spending more time on these adjustments I know. I've now got a real bike that is a lot different from the one I bought a month ago. Went riding the other day and a guy on a WR450 came up and said "I can't believe how easy your bike started cold". All I could say was TT.com. Thanks again to everyone on the forum and to the forum owner. Now if anyone read to the end of this message, I have a question I haven't read about. My manual says 95 octane and the most I see around is 92. Any comments?
